MACHINE Specification of To all whom it may concern: Be it known that I, OTTO THIEME, a citizen of the United States, residing'at St. Louis, Missouri, have invented a certain new and useful Improvement in Marginal Releases for' Type-Writing Machines, of which the following is a full, clear, and ex: act description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part-of this specification, in which Figure 1 is a fragmentary view showing my improved device as applied to an ordinary typewriter. Fig. 2 is a portional view showing my device as viewed from the rear of the machine. Figs. 3, 4 and 5 are detail views of my improved carriage stop.

My invention relates to an improvement in a carriage of a typewriter, whereby the carriage will always be stop edwith the left hand side of the sheet in the same relation to the printing mechanismof the machine in order to form a margin in the proper place. I have also provided a device for; acting upon the stop on the carriage to allow this fixed marginal distance to be changed at any time without having to readjust the stop on the carriage.

Referring to the drawings, 1 designates the frame of the typewriter generally.

a 2 designates the carriage mounted to operate on top of the frame of the typewriter.

3 is a rack supported at either end in any suitable manner on the typewriter carriage 2.-

4 is a stop which is adjusted as to position on the rack 3. This stop device is comprised.

. the rack "of the pin 14 is. a spring 17 bearing-against of a body portion 5 having side projections or wings 6 and 7 extending downward therefrom, and inwardly projecting lugs 8 and 9 which form a slot or groove 10 in which 3is mounted. Extending transversely of the body portion 5 is a plunger 11 extendin through the sides of the portion 5, Whic plunger is notched as at 12,to pass over the rack 3 and has formed at one edge of the notch a tooth l3 to'engage the teeth on the rack. Projecting from one side ofthe'plunger 11'is a pin 14 moving in a groove 15 of the body portion 5. side of the pin 14 in the groove15is a screw plug 16 acting as a-stop-when the pin 1a. engages therewith, On the opposite side,

the body portion 5 at one side, and the pin at the other, which spring tends to push the plunger 11 outward so that the tooth 13 engages between two teeth on the rack 3. .By pressing on the head 18 of the plunger 11 the tooth 13 may be disengaged from the rack 3.

Extending longitudinall at one side of the body portion 5 is a Sll(lI1g stop member 19. This member is comprised of a'cylin drical body portion 20 which is cut away at 21, as is also the body portion 5 for clearance purposes. Atthe lower extremity of the cylindrical portion is a lateral projection or foot 22, and at the upper extremity the portion 20 is reduced in diameter at 23, to form a seat for a knurled head 24 suitably held in position by means of a stud 25. The knurl head 24 is slotted to allow a pin 26 fixed on the upper side of the body portion 5 to pass therein. The foot 22 may be moved by means of the head 26 away from the fixed portion 30 of the machine, and up- 'wardly within the openin in the sliding block 5, so as to be with rawn from the path of the fixed portion of the machine, and the head 24 then slightly rotated to be supportednpon the pin 26 to retain the foot 'in this position. By this means the block 5 may be retained on the machine, but does not perform its usual function.

Projecting from one side of the cylindrical portion 20 is a pin 27 movin slot 28 in the body portion 5. A spr ng 29 tremity and a fixed tion 5 at the other extremity, tends to hold the stop with the foot 22 in its lowestposi tion.

The framel of the machine is formed at the foot 22 may lmpinge in, the travel of the carriage. The frame portion 30 is, however, adapted to pass under the body por- .tion of the stop 4, and if the foot 22 be pressed upward against the action of the spring 29, it also may clear the frame porany desiredpoint. I

r In order to move the foot 22 upward I have provided a lever 31 pivoted at 32 on a bracket 33 attached to the machine frame,

, 'said lever 3l extending. to a position adjaeat; the frame portion 30 at one end and at the other end having a lateral projection 34 Patented June 27, 1911. Application filed September 23, 1910. Serial N 0. 588,436.

in a

adapted to engage the pin 27 at one ex portion of the body porthe rear with a' p0rt-ion30 against which,

tion 30 and the-carriage thereby stopped at with an opening therein for a rod 35. This lever 31 is also provided with a lateral projection 36 adapted to engage a portion of a the bracket 33 to form a stop for the movement of the lever. On the other side of the pivot 32 of the lever 31 from the stop member 36 is a retractile spring 37 attached at one end to the lever and at the other to the bracket 33, which spring tends to hold the left hand end of the lever 31 in lower position and out-of engagement with the foot 22. The rod 35 has several lock nuts 36' at- I tached above the end 34 of the lever 31.

This rod is suitably bent or shaped to be attaclied .t,o a lever 37 by screw threaded conncction'and a lock nut 38. The lever 37' is connected to an ordinary form of a key bar 39 pivoted at 40 and having a key 41 at one end. A spring 42 is connected to the key bar 39 and a fixed member 43 of the frame to hold the bar in engagement with the cross bar 44 on the frame.

It may be seen from Fig. 2 that the stop member 4 is cut away for clearance of other parts of the machine not necessary to be described, and that the frame portion is adapted to support a lever which is also not necessary to refer to, as forming no part of my present improvement.

When the operator adjusts the stop 4 on the rack 3, by moving the plunger 11, until the stop is in desired position, it is apparent that the projecting foot 22 will engage the frame portion 30 at the same point in the travel of the carriage, and therefore, the operator, when the carria e arrives at the end of the line in moving t e carriage backward, will always bring the carriage to the same relative position to the printing mechanism and thereby form a proper margin to the page of printing. If, however, it is desired to change the mar in at any particular line, as at the end 0 a paragraph, it is only necessary for the operator to actuate the key 41, which through its connections with the lever 31 will move this lever upward so that it will en age the foot 22 of the stop 4 and so move t is stop out of position'to impinge the frame portion 30 and the starting pint of the carriage may thereby be co'ntroiled b the o erator.

It should be un erstoo that I do not confine the use of my improved adjustable stop to a typewriter carriage in which it is desired to maintain the mar in at any special distance from the edge 0 the sheet, as it could also be used to regulate the osition of a column of figures, for examp e, or a column of any description. In which case I should employ an additional stop illustrated at v4 which would'be used to stop the carriage at the desiredpoint to form a roper margin on the sheet. This stop woul be in structure similar to stop 4 without the adjustable foot 22.

-chine,' and a manually I am aware that minor changes in the construction, arrangement and combination of the various parts of my device may be made without departing from the spirit and scope of my invention which is indicated in the accompanying claims.
